Abstract: PURPOSE:To improve the flatness of the surface of a polycrytstalline silicon film in a groove by a method wherein a silica thin film is formed by spin coating after the formation of a polycrystalline silicon film, the silica thin film is subjected to etching foir the partial exposure of the surface of the polycrystalline silicon film, and then the polycrystalline silicon film, and then the polycrystalline silicon film is subjected to etching. CONSTITUTION:A polycrystalline silicon film 16 is formed on a silicon substrate 11 provided with a silicon oxide film 12, silicon nitride film 13, and a groove, whereafter a silica thin film 18 is formed by the spin coating mkethod. The silica thin film 18 is then subjected to anisotropic dry etching, for the exposure of the polycrystalline silicon 16 except in the groove. A process follows wherein the polycrystalline silicon film 16 is subjected to etching by anisotropic plasma IA. A relatively flat surface appears in the groove because at its center etching is less effective due to the remaining silica film 18. An element isolating region is formed when the remaining polycrystalline silicon film 16 is converted into a silicon oxide film 17 by thermal oxidation.

IPC: H03K3/037
Filed: 1982-10-20
Abstract: PURPOSE:To eliminate the holding time for data latch with a simple circuit constitution by providing two latch circuits which have a series relation and work synchronously with each other and performing both fetching of data and decision of latch at a time by the 1st latch circuit at a rise of a latch command signal. CONSTITUTION:The data arrives at a point (a) before a latch signal phit1 is produced, and the 1st input side transistor TRT1 and the 2nd feedback TRT4 are turned on with the 1st feedback TRT2 and the 2nd input TRT3 turned off respectively. The logic levels are set at ''1'' and ''0'' at points (b) and (c) respectively. The data obtained by the latch command signal of the previous time is delivered at a point (e). The above-mentioned transistors are all inverted by a latch command signal phit1 at a time point t1, and the data fetching is over. Then points (d) and (e) are set at ''0'' and ''1'' respectively. Then all transistors are inverted again by a latch release signal at a time point t2, and the 2nd latch circuit L2 holds the data at the time point t1 and then delivers it from the point (e). In such a way, the circuit constitution is simplified and the holding time that fixes the latch contents can be totally eliminated.
